This is not my story

An author and his hero embark on a genre-bending journey to find the right story. The brave spaceship captain is surrounded by flying saucers. Though the situation appears dire, he knows just what to do ... um, wait! The captain - ahem, boy - tells the author to stop the action: He's got it all wrong. This is not the boy's story. He belongs in a different story. Hmm. Maybe a story about the quickest cattle wrangler in the West? No! A dragon-slaying knight? No! A vampire's next victim? No! Will the author ever come up with the right story? A hero who talks back to his creator? Kids won't be able to look away!.
